Diorama will tilt your mind

See, now this is the kind of game I want from my iPhone -- the accelerometer isn't just a gimmick thrown in with the gameplay, it's the actual premise of the game. Diorama is a weird little Marble Madness-style maze game, but the catch here is that instead of just tilting the accelerometer to move the ball (which you do), the level of the game actually moves with you, so that you get a stereoscopic kind of effect, as if the stage is real inside your iPhone's screen. Tough to explain, but as soon as you see it above, you'll know what it's like. We've seen this kind of effect before in apps like MotionX's Dice roller, but in this case, it's actually part of the game -- you can only find the paths to take around the stages by actually tilting the device. And for extra 3D viewing, there's an actual 3D mode, so if you happen to have red and cyan glasses around, you can switch on the mode for anaglyphic 3D.

The app is the first iPhone release from a company called Drömsynt, and though the initial reports on iTunes say the game is pretty tough (it is a pain navigating the quickly-moving ball around those pathways), for just 99 cents, it's definitely worth downloading, if only to see how it works. So many apps just throw in a few iPhone-specific features as afterthoughts, but it's refreshing to see a game like this (or like Zen Bound, which really depends on the multitouch screen) rely on the originality of the hardware itself.
